The extreme heat and humidity will last for four days, with temperatures soaring up to 25 degrees above the average into triple digits. The entire region has been placed under various types of heat advisories, with Boston declaring a heat emergency preemptively. In light of this, some school districts without proper cooling have decided to close their buildings this week to protect students from the sweltering conditions. On Tuesday, temperatures are expected to surpass 90 degrees, with a possibility of reaching 100 degrees by Wednesday and Thursday. However, it will feel even hotter, with a predicted heat index of 103 degrees in Boston on Wednesday. A staggering 11 million people in New England are under advisories for excessive heat and elevated temperatures starting on Tuesday and lasting until Friday evening. These alerts are typically issued when "feels like" temperatures are expected to exceed 100 degrees. An excessive heat watch has been issued for multiple suburbs surrounding Boston as well as parts of New Hampshire, Maine, and Connecticut due to potentially dangerous conditions with forecasted afternoon heat index values reaching up to 105 degrees. This watch also covers north-central Connecticut.
Boston and the rest of Massachusetts, with the exception of the Cape, Vermont, southern New Hampshire, and northern Rhode Island, will be under a heat advisory from Tuesday through Friday due to high temperatures (95-104 degrees) and elevated humidity. Dew points are expected to rise significantly throughout the week, reaching the upper 60s and potentially even breaking 70 degrees by Wednesday. As a result, conditions will feel very hot and uncomfortable. The heat index is projected to climb into the mid-90s on Tuesday and surpass 100 degrees on Wednesday and Thursday, creating dangerous heat conditions as our bodies struggle to cool down. Even in the evenings, there will be little relief as the sinking air prevents heat from escaping. Temperatures around sunset will remain in the range of 80-85 degrees and overnight lows may not drop below 70 degrees starting on Tuesday night.
